DSA Sheets

Two problem sheets with LeetCode and GeeksforGeeks links and progress tracking that lives in the browser. Live at https://hm0.org.

• A2Z DSA Sheet (/, one page per topic at /topics/<slug>): problems/problems.json, with topic names, URLs and descriptions in lib/topic-meta.ts.
• SDE Sheet (/sde-sheet): problems/sde-sheet.json, topics -> patterns -> problems. A problem that is also on the A2Z sheet names it in a2z; it then shares that problem's links and its tick (solve it once, it's solved in both sheets). leetcodeurl / gfgurl on an SDE entry fill in links the A2Z entry lacks.
• app/: the pages, plus sitemap, robots.txt, manifest and social images.

The site is a static export (next build writes out/), served by nginx.

npm install
npm run dev        # http://localhost:3001
npm run build      # static export in out/
npm run preview    # serve out/ on http://localhost:3001
